In her artist statement, the artist said: "I would like to live in Rainbow Land and paint and paint and paint".
Her mother Neeltje Bruce says she seems to live like that anyway.
"She has been painting since she could hold a pencil and that is all she does. She does it in her room; she does it wherever she is. She has got a pink craft bag that is full of felts and that goes pretty well everywhere."
Mrs Bruce said Jayne has a very strong sense of colour and Rainbow Land is her creation.
"It's somewhere inside her. She has always put the most outrageous colours together and they look fantastic."
Jayne Bruce will be presented with the People's Choice Award and her prize of $1000 today at the IHC Art Awards at the Michael Fowler Centre, Wellington.
